Ukraine’s best answer to Russia’s jet Shaheds is its own jet Shahed, turned around to hunt them

Russia's latest jet-propelled Geran-4 and Geran-5 one-way attack drones fly at 500 km/h or more, nearly three times as fast as an older, propeller-driven Geran-2.

That's too fast for many of Ukraine's air defenses. In particular, the inexpensive interceptor drones that Ukrainian forces deploy by the thousand.

Russia launched more than 2,700 jet Gerans at Ukraine in September, and Ukraine is shooting down only about 55% of them, according to Ukrainian President Volodymyr Zelensky. The speed disparity is a big part of the problem.

Ukrainian forces are scrambling for new defenses against the speedy Gerans. Among the best is actually a Ukrainian take on the Geran-4 and Geran-5: a fast, jet-propelled one-way attack drone that the Ukrainians have modified for air-to-air use.

Against jet drones, the air-to-air Bars have a hit rate of around 30%, Zelensky said during a joint press conference with German Chancellor Friedrich Merz in Kyiv on 4 October. "The Bars have shown positive results," Zelensky said. "They currently have the highest percentage. Others are also catching up."

In July, Ukraine and Germany agreed to jointly produce Bars, with Germany financing the first phase. Ukraine has reportedly been launching Bars at targets on the ground since at least the summer of 2025. But it was only recently that clear photos and videos of the drones have circulated.

Over the weekend, Ukraine’s 1021st Anti-Aircraft Missile and Artillery Brigade released footage of one jet drone hunting another. Observers identified the interceptor as a Bars and its target as a Geran-5. After launching from an elevated ramp with help from a rocket booster, the drone's operator—seeing what the drone saw through a front-facing infrared camera—steered the drone toward the Russian drone, possibly destroying it.

Exactly how the operator controlled the Bars—whether by satellite or mesh radio or some other command and control system—is unclear. Equally unclear: what kind of warhead a Bars would employ in the air-to-air role. Many smaller interceptor drones lack warheads. Instead, they simply slam directly into their targets, wrecking them in the collision.

Mystery drone

Bars isn't small. It likely packs an explosive warhead. Potentially one that the operator can remotely trigger when the interceptor passes near its target.

Bars is adaptable. Its maker has reworked it from a 22-kg warhead and a 700-km range to a 60-kg warhead and a stated range of more than 1,000 km, and a heavier variant can carry a 105-kg warhead.

In the air-to-air interceptor role, long range is terribly important but speed is everything. There's an obvious way for the Ukrainians to boost the Bars' speed from its reported 700 km/h top speed to potentially even faster. They could shrink the drone's warhead and its fuel load, making it lighter in order to make it faster.

That may explain how a Bars can chase down a Geran-5 even as the Russians, by one Ukrainian analyst's estimate, try to push the Geran-5 toward 700 km/h or more.

Cost is important, too. Russia churns out Gerans for an estimated $100,000 or so per drone. The cheaper the drone, the more copies the Russians can fling at Ukrainian cities. If it takes three or more interceptor drones to take down each of those 2,700 jet Gerans, Ukraine may need to deploy 8,000 to 10,000 interceptors a month.

Ukraine already builds more than 2,000 Bars a month, its maker says, but mostly in strike versions. How many go to air defense, and how much each costs, isn't public.

The supply of small jet engines could be a constraint. “Engines are a key element; we really import them in large quantities,” Zelensky said in an interview with Financial Times. "There are also domestically produced engines, but there are not enough of them.” A Ukrainian-made engine for Bars passed final tests in September.
